IMPROVEMENT IN WATCH-KEYS.

TO ALL WHOM IT MAY CONCERX:

lle it known that l, E. M. KI.\in.\LL, of Toledo, in the county ofLucas, and State 0t Ohio, have invented a new and useful Improvement inWatch-Keys; and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to theaccompanying drawing, making a part of this speeifieation, in whichFigure 1 is a side view, on, an enlarged scale, of a watch-keyconstructed according to my invention.

Figure 2 is an edge view of the same, also on an enlarged scale.

Similar letters of reference indicate corresponding parts in bothfigures.

It is 1 frequent occurrence that the cases of a watch open with suchditlicalty that the thumb-nail is not still' or strong enough to openthem in the usual manner, which necessitates the use of some article orimplement for the purpose, such, for instance, as a knife-blade, whichnot only causes eonshlerahle trouble, hut alsomuch vexatious delaywhenever for any purpose it is desired to open the watch.

This invention is designed to obviate this inconvenience, and itconsists in the construction of the windingkey of a watch with a bladeor sharp edge, formed thereon in such manner that the said keyconstitutes a very eilicient implement for opening the cases, and onewhich may be used with great convenience, and without any ap n'eeiableless of' time.

To enable others to understand the nature and construction of myinvention, I will proceed to describe it with reference to the drawings.

The sot-ket" ol' the winding-key is shown at It, and 6 represents thehead or thumb-ring" thereof, the socket being made of any usual orsuitable form and material, and the thumb-ring being made of metal wireor other proper material, and fitted into or attached to the socket inany appro 'iriate manner. Formed at the innermost portion of thethumlrring, where it is joined to the socket, is a short neck, (1, uponwhich is placed the swivel c, by means of which the lacy is attached tothe guard or chain of the watch. The outermost portion or end at thethumli'ring 7) is made llat upon each side, but with the said sidessloping towards each other in such manner that. the outer circumferenceof the aforesaid end of the thumb ring is brought to a moderately sharpedge, as shownnt Z1, and more plainly indicated in '2, or, in otherwords, the said outermost end or portion of the thumh-rin is t'ormedinto a kind of blade, the edge of which may be forced under the edges ofthe watch-case in order to open the said case.

When it is desired to time open the watch-cas the sharp cdere oi theblade (1 is inserted underneath the edge of that lid there-d which itdesired to rage, or open, and the said blade is then pushed outward inthe same direction with reference to the lid that the thumb-nail ispushed outward in opening the case with the thumb-nail in the usualmanner, which causes the lid to be forced outward and opened in the sameway.

By this means the wntclecasc may he very easily and conveniently openedwithout danger of breaking or injuring the thumbnail, as in the commonmanner of opening the case, and without the delay and trouble occasionedby using an implement for the purpose not specially design d therefor.

What 1 t-Jllli as new, and desire to secure by Letters Patent, is-
